To aZZ whom it may concern:

Be it known that I, OTHO M. OTTE, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of certain new and useful Improvements in Window-Sashes, of which improvements the following is a specification.

In `applicationsv iiled of even date herewith I have described and claimed certain improvements in metal sashes, the improve-- ments in one of said cases consisting of a sash formed in what for convenience is termed a threeieee sash, consisting ofthree parts or mem ers. In the other case the sash consists of two parts or members-to wit, a frame with cross-bars and muntins and one of the glazing-strips, the second member being formed by a removable glazing-strip.

The invention described herein consists of a sash which for convenience is termed a one-piece sash, the lazing-strips bein formed integral with the Irame, muntins, an cross-bars.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of my improved sash. Figs. 2 and 3 are sectional views on lanes indicated, respectively, by the lines I II and III III, Fig. 1. Figs. 4 and-5 are'side and edge views of a cross-bar, and Fig. 6 is a side view of one of the Inuntins.

In the ractice of my invention I employ-a structurall shape which is approximately that of an I-beam, consisting of a core or central portion l and flanges or plate portions 2 and 3. To form the frame or skeleton of the sash, such a structural shape is bent to the form of a U, or, if desired', may be bent to bent, the flanges 2 project outwardly from the sides of the frame, forming a guide-groove for the reception of the guidin -plate 5, secured to or embedded in the sie wall of the window-opening. The inwardly-projecting flan es 3 ofthe frame form glazin -strips for retaining the glass in position. o form the muntins, a structural sha e similar to that employed for formingl t e frame has its flanges cut away at its ends, so as to form tongues 7, which will project between the inner flanges of the upper cross-bar or upper rail of the sash andthe flanges on the lower rail of thel sash. These tongues are secured in position by suitable rivets or screws. The.

cross-bars are formed of sections, as shown in Figs. 4. andl 5, the flanges at the end of the sections bein cut away so that the projecting core will orIn tongues 8, which will project in between the flanges of themuntins and side bars of the frame. are secured in position by means of screws or rivets passing throu h the flanges and tongues. In placing t e-glass in a sash of this construction the lower panes are slid down between the muntins and side bars into position, the cross-bars also,I slid down, the ton e sliding between the flanges of the vertica parts or members and when in position are secured by screws.

manner, and the next cross-bar or end rail, as the case may be, is placed in position. The end rail has the flanges cut away at its ends to form tongues which project into .recesses formed in the side bars of the frame by cutting away the cores, as clearly indicated in The next row ofl panes of glass are next inserted in the samev T-hesc'ross-bars shape, the shape being such that the outer 2.
